Answer:

acceleration of the particle as a function of time is given as

a(t)=-\frac{ks}{t}

and position of the particle as a function of time is given as

x(t)=ut+\frac{at^2}{2} \\x(t)=V_{0}t-\frac{\frac{ks(t)}{t}t^2}{2}

x(t)=V_{0}t-\frac{kst}{2}

Explanation:

we have given,

v=v_{o}− ks

at t=0, s=0

therefore initial velocity,u

u=v=V_{o}

v=u+at.........(1)

we know from first equation of motion

let acceleration at time t be a(t), and position be x(t)

put value of v,u and a in equation 1

we got,

V_{o}-ks=V_{o}+a(t)t

Therefore,acceleration of the particle as a function of time is given as

a(t)=-\frac{ks}{t}

and position of the particle as a function of time is given as

x(t)=ut+\frac{at^2}{2} \\x(t)=V_{0}t-\frac{\frac{ks}{t}t^2}{2}

x(t)=V_{0}t-\frac{kst}{2}

a baby carriage is sitting on the top of a hill that is 21 m high. the carriage with a baby 75kg. the carriage has what energy?
lara31 [8.8K]

Answer:

It has potential energy

PE = 15450.75 J

Explanation:

we know its potential energy because the carriage is not moving, although it can

PE = mgh

in this case, m is 75, h is 21, and g is always 9.81

plug these in: PE = (75) (21) (9.81)

your answer: PE = 15450.75 J

Which set of atoms will form an ionic compound?
Oksanka [162]

Answer:

The answer is A)

Explanation:

An ionic compound is formed when one atom donates one or more electrons to one or more atoms of another element. Calcium has two valence electrons, which are donated to an atom of oxygen. So, an ionic compound is formed in the reaction involving one calcium atom with an oxygen atom.
